Question

我一直遇到从EditText到TextView的文本出现问题，EditText正在自定义操作栏中膨胀，我知道解决方案非常简单，但我无法找到解决方法，我能够在其他活动但未能在此活动中执行此操作，下面是我的代码：

ActionBar mActionBar = getActionBar();
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);

LayoutInflater mInflater = LayoutInflater.from(this);
View mCustomView = mInflater.inflate(R.layout.search_customactionbar, null);
ImageButton mstartsearch = (ImageButton) mCustomView.findViewById(R.id.msearch1);
mActionBar.setCustomView(mCustomView);
searchbox = (EditText)findViewById(R.id.searchbox1);
mActionBar.setDisplayShowCustomEnabled(true);

searchQuery = (TextView)findViewById(R.id.itemName);
searchQuery.setVisibility(View.INVISIBLE);

mstartsearch.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
      searchQuery.setText(searchbox.getText().toString());
      searchQuery.setVisibility(View.VISIBLE);

  }
});

当我运行此代码时，我收到以下错误：

        at android.view.View.performClick(View.java:4472)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:688)
        at dalvik.system.NativeStart.main(Native Method)

问题出在哪里？
